GAS-GENERATOR.

Specification of Letters Patent.

Patented J an. 21, 1913.

Application filed August 27, 1909. Serial No. 514,888.

To all whom it may concern:

Be it known that I, MA RICE DAVIOION, a citizen of the Republic of France, residing at 4-6 Rue de Chateaudun, Paris, France, engineer, have invented certain new and 'useful Improvements in Gas-Generators, of which the following is a specification.

This invention relates to improvements in gas generators and has for its object to provides. gas generator the vat of which is so suspended as to keep the approaches of the hearth completely clear.

One of the essential features of the invention consists in the device for the injection of air into the generator and which comprises in combination a bowl shaped revolving hearth provided at the center with a conical cap extending much higher up than the edges of the bowl whereby the materials are caused to move down toward the edges thus preventing any obstruction in the air pipe which occupies the center of the cone. The importance of such an arrangement is very great by reason of the particular nature of the materials to be burned in the generator and which consist of extremely poor schists, and waste of which no use has hitherto been made and which gives rise to slag "having a great tendency to stick and prevent the operation of mechanical memhere not altogether suitable for the treatment of such materials. For the same purpose, wide ribs are formed on the generating lines of the cone, and radial arms project from the latter so as to carry the slag forward. The base of the said arms is so arranged as to be immerged in the water, in order to keep up the required rigidity. With such an arrangement the agglomeration of the slag on its arrival in the hydraulic joint is no longer to be feared.

Besides these essential features, the generator according to this invention comprises several particular arrangements, such as the hydraulic joint of the air, pipe, the lagging of the latter, the constant level at which the said joint is held, the removable head of the air pipe, all of which contribute. to the proper operation of the generator. The support of the generator chamber, which is of course independent of the revolving hearth, is so fitted as to allow of easy access to the hearth.

One embodimentof my invention is shown in the accompanying drawing, in which is shown partly an elevation and partly a vertical sectional view of the gas generator.

The apparatus comprises a generator chamber 1 of fire-clay and provided with an outer lining of sheet metal 2. Such generator chain 161' rests on a metal frame 3 formed of bars so assembled as to constitute a training of polygonal shape. Two of the said bars extend outward and rest on col-- umns of brick-work 4, outside the generator and which support the whole of the apparatus.

Attire lower part is arranged a truncated cone shaped hearth 5, mounted in ball-bear ings and enabled, through the medium of the p1nions'7 and 8, to receive rotary motion from an operating shaft. The conical portion of the hearth ,comprises the cone 17 and the head 18 of the air pipe, such head being'removably fitted inv a housing in the top of the pipe 13 associated with the said cone. In the cone are formed strong ribs 19, which cooperate with the radial arms 9 to carrythe slag forward, the said arms 9 are thin, and directed approximately radial to the cone.

The generator chamber 1 is provided at the outside with several plowshares such as 10 which act energetically on the ashes on account of the rotar motion of the hearth. Another fixed plows are 11, higher up than .any of the others, produces the automatic removal of the ashes at the outside.

The air is supplied by a pipe 12 located at the lower part of the gas generator and which is connected with the air pipe 13 through the medium of a hydraulic joint 14 wherein the water is kept substantially at the same level by means of an outer reservoir (not shown) communicating with the tube 15 of the joint. The hydraulic joint is, furthermore, protected against excessive evaporation by a bad conductor of heat or lagging 16, which. separates it from the pipe 12.

The employment of an isolating lagging 16 between the air supply pipe and the cup 14 of the hydraulic joint is particularly useful in case that hot air should be used. In such case, it will be suitable also to provide the pipe 12 with a prolongation 20 which reaches up to the head of the air pipe 13 for the purpose of reducing evaporation as much as possible.

21 designates a pipe for drawing oil? any water which may get into the pipe 12,

Claiinsv 1 1. In a gas generator with a revolving ash-pit having a flat annular bottom and a central conical part and a fixed generator chamber, disaggregating arms projecting from the central conical part substantially toward the lower edge of the generator chamber and ribs extending onto both the conical part'and the bottom of the ash-pit substantlally to underneath the lower edge of the generator chamber.

2. In a gas enerator with a revolving ash-pit the com ination of several low and narrow shares secured -to the generator chamber and adapted to stir the cinders in the ash-pit and of a high and wide share secured to the generator chamlrer and adapted to throw the cinders out of the ash-pit.

In a gas generator with revolving ashpit connected by a hydraulic joint with the air supply pipe, theombination of a fixed supply pipe, of a collar which is a bad condoctor of heat around the said pipe, of an annular cup of water around they said collar, and of a bell secured underneath the ashpit and dipping into the said cu In testimony that I claim the oregoing as my invention, I have signed my name in presence of two subscribing witnesses.
